Hi, I regularily use etags, but I found annoying that it doesn't index fortran 90 modules. An option is to use "ctags -e", which actually has support for fortran 90 modules. However, since I support emacs, I rather prefer using etags with the option --regex="{fortran}/[[:blank:]]*module[[:blank:]]+[_[:alnum:]]+/i" I wonder if this regex could be added to etags, so that it could index fortran 90 modules by default. Thank you, Luca
